If you think that simple „dd bs=1M count=512 if=/dev/zero of=test conv=fdatasync“ disk benchmarking is not enough – you’re completely right. There are not so many tools benchmarking your disk, one of the most used is Bonnie++.

You must use the „-u“ switch when running as root.
usage: bonnie++ [-d scratch-dir] [-s size(MiB)[:chunk-size(b)]]
[-n number-to-stat[:max-size[:min-size][:num-directories]]]
[-m machine-name]

Version: 1.03e
As you can see from last message, whole benchmark is controllable via command line. According recommendation I’m using -n 1024 (number of files), whole line can be similar to:
linux-fot6:~ # bonnie++ -u ji -d /tmp/bench -n 1024
As I’m running bonnie from root, I have to specify common user (-u ji). Output:
linux-fot6:~ # bonnie++ -u ji -d /tmp/bench -n 1024
Using uid:1000, gid:100.

You can see output in good format, anyway if you plan to execute more tests, maybe more harddrive, etc… utility compiled with Bonnie++, bon_csv2html can be very handy:
linux-fot6:~ # echo "linux-fot6.site,31960M,105174,98,468152,34,212857,18,109460,98,649174,40,+++++,+++,1024,75103,81,967814,100,35173,38,75187,79,1124432,100,23450,31" | bon_csv2html > /tmp/speed.html
In my case, generated html file looks like:
